Abstract: 1377390 Transistor circuits ELECTRIC FUEL PROPULSION CORP 17 Dec 1971 58707/71 Heading H3T [Also in Division H2] A circuit for supplying a square wave voltage to a load 52 from a D.C. source 50 comprises a thyristor 54 and a diode 60 which is supplied with positive and negative pulses from a source 70 to cause the diode to conduct in forward and reverse directions respectively thereby commutating the thyristor. The diode is designed to have a turn-off time, i.e. the time required for its reverse conduction to be cut off, which exceeds the turn off time of the thyristor 54. The pulses are supplied to the diode via a transformer 64, the positive pulses causing the diode to conduct in a forward direction whilst the negative pulses cause reverse conduction of the diode thereby switching off the thyristor. A transient suppression circuit 80 is connected across the thyristor and the pulse source 70 is shown in detail in Figs. 3, 4. A suitable pulse X is applied to terminals 100, 102 enabling a multivibrator 104 to switch on a transistor 106 so that current flows through the primary winding 114 of a transformer 112. The pulses induced in the secondary windings 110, 108 switch on transistors 116, 118 of the inverter shown in Fig. 3 to supply a positive pulse to the primary winding 76 of the transformer 64. When the multivibrator 104 is switched off, the inductive surge in the winding 114 is sharpened by a differentiating circuit 130, 132, 134 and causes a multivibrator 140 to switch on a transistor 144. The pulses induced in the secondary windings 150, 154 of a transformer switch on transistors 160, 162 to supply a negative pulse to the winding 76. In a modification, Fig. 5 (not shown), a high frequency A.C. source charges a capacitor connected in series with back-to-back thyristors or a triac and the diode. The A.C. source may be the one kilocycle per second supply in an electrical vehicle.

Title: Manufacture of Integrated Circuits
IPC: H01L29/51
Filed: 1979-05-24
Abstract: A silicon nitride layer 6 on a silicon dioxide layer on a silicon substrate are initially etched off where field oxide regions 2, 3 and 4 are to be grown to isolate FETs and diffused lines. A polysilicon layer 11 is laid down and oxidised on its surface and nitride layer is then formed. The nitride layer is masked and etched to leave a button (13) where connection is to be made to a polysilicon line 11 on the field oxide region 3. The polysilicon is then etched to leave an FET gate electrode and the said line. The exposed nitride layer 6 and underlying dioxide layer are etched off to expose source and drain regions for the FET and a diffused line between field oxide regions 3 and 4. Dopants are introduced e.g. by ion implantation or diffusion. An oxidation step ensures that oxide margins 475 are grown on the exposed edges of the polysilicon gates and lines. The nitride buttons are etched off where connections are to be made. Further insulation may be built up by depositing silicon dioxide 410 and etching where connections are to be made. Finally a pattern of conductors 20 is etched, these making contact with the polysilicon line 11 where it was exposed by removing the nitride button and with the source and drain of the FET. The diffused line between field regions 3 and 4 may constitute the connection to the gate of the FET. The polysilicon layer may be replaced by an oxidisable metal e.g. molybdenum. <IMAGE>

Title: Vapour deposition of metal in plasma discharge
IPC: A63H7/00
Filed: 1979-07-20
Abstract: A method for ion plating an electrically conducting substrate with a metal comprises generating a plasma discharge in an inert gas, e.g. argon or helium using DC, RF or DC biased RF, introducing the vapour of a volatile compound of the plating metal and decomposing the compound in the discharge using pyrolysis, microwaves, photolysis or chemical reduction. Suitable compounds include the halides, carbonyls, nitrosyls, alkyls, aryls or hydrides of W, Ta, MO, Nb or Cr. The discharge current required is proportional to the area of substrate to be coated, but also depends on the plating gas composition and flow rate with a minimum value of 0.5mA cm<2>. By reducing the input of the metal compound at intervals, the deposited coating may be sputter cleaned during the plating process. The method is used for plating the inner surface of a tube.
